The Chemistry of Chloroform

Introduction

YouTube Video

Chloroform is a colorless, sweet smelling, dense liquid; of mostly organic origin (Brown, red, and green seaweeds), but was first made in july of 1831 by, Samuel Guthrie. Then was independently made by Eugène Soubeiran in France, and Ludwig von Liebig in Germany.

I chose Chloroform because, i’ve always found the qualities of Chloroform interesting, and i wanted to “Debunk” the common misconceptions about Chloroform.

Chloroform has affected my life in many ways.

It gave a large portion of my family that lived after 1834, cancer in some form

it killed some of my family

It created the possibility to make HCFC-22, a common refrigerant. and other products, me and my family used, when i was younger.

Composition of ...

The main two components in Chloroform are

Methane (CH4)

And

Chlorine(Cl)

Composition of Methane and Chlorine

Methane, which is Tetrahydrocarbon by scientific terms has the Formula of CH4.

Methane is the simplest alkane, and is the main component in natural gas

Chlorine, has no common name, and has the atomic symbol as Cl

Chlorine is the “backbone” of most salts and some minerals (I.e. Sylvite [KCl])

Chloroform by itself has a chemical compound of CHCl3

Chemistry's Role

Chemistry takes role in making and refining Chloroform.

First they initially combine Methane and Chlorine (CH4 + Cl2 → CH3Cl + HCl), they break down or remove the Hydrochloric acid

then they again combine the new compound with chlorine (CH3Cl + Cl2 → CH2Cl2 + HCl), and again break down or remove yet more Hydrochloric acid.

They once more, combine the new compound with chlorine (CH2Cl2 + Cl2 → CHCl3 + HCl) and once more break down or remove the Hydrochloric acid

in most case chloroform goes under one more stage of cloronation (CHCl3 + Cl2 → CCl4 + HCl) which they then distill to collect four different chloromethanes. chloromethane, dichloromethane, chloroform, and carbon tetrachloride.

Background Research

Methane

Methane, is naturally produced by the human body, decay of natural materials, and by geothermal area’s such as Yellowstone

It also exists naturally in pockets, underground

also made by man, during the cultivation of rice, fossil fuel production, biomass burning, waste activities, and Animal Husbandry

Can be explosive, at levels as low as 5%

Can displace oxygen

Chlorine

it was also used in WWI, as a biological weapon

When in contact with soft tissue, it produces an acid, and is usually lethal

Chlorine is used in pools as an antibacterial, used as a main component in the manufacturing of paper, as a pesticide, solvents, and used to make rubber

Chlorine is made in a lab, by reaction of hydrochloric acid and manganese (IV) oxide. [4 HCl(aq) + MnO2(s)MnCl2(aq) + 2 H2O(g) +Cl2(g)]
